Backport GLib Windows socket fixes: WSAENETRESET + Windows FD_READ condition flag still set on recoverable UDP socket errors

See https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1616

This causes issues in rtspsrc/gst-rtsp-server on Windows if for some reason the packets we sent out reach the TTL. Especially in case of rtspsrc that's annoying as those are either just RTCP receiver reports or the few dummy packets we sent in the beginning for NAT hole punching.

Should wait until it's in GLib to prevent different behaviour.
